OIL-DISCHARGE JET.

Specification of Letters Patent.

Patented Apr. 11, 1922.

Application filed September 23,1921. Serial No. 502,785.

.To all whom it may concern:

Be it known that we, HENRY F. BLACK- BURN and WILLIAM J. CUMMINGS, both citizens of the United States of America,

- ural gas and another object is to make the gas engage the oil in a direction approximating the direction of the flowing oil which is being discharged so that the flow of oil will not be impeded but pushed upwardly and saving the force of the momentum of the oil. Another object is to provide means for regulating the passage of gas into the oil line so that more or less gas can be let into the oil line and also so that the gas passages can be closed entirely in case of necessity. One advantage of this invention is that no gas or air or steam is necessary for lifting the oil out of the wells and so that pressure on the oil sands by gas or air or steam introduced. from the surface of the ground is avoided.- .Another advantage is that if there is not enough natural gas to lift the oil out of the wells, gas or air or steam may be introduced from the surface for lifting the oil out of the well without pressing onthe oil sands. This invention is an improvement shown in the application filed by Henry F. Blackburn and Earl L. McMillen .on Sept. 2, 1921, Ser. No. 498,117, for oil discharge jets. Other objects and advantages will be fully explained in the following description and the invention will be'more particularly pointed out in the claims. X

Reference is bad to the accompanying drawings which form a part of this application.

Fig. 1 is a side elevation of the jet without the connections. Fig. 2 is a vertical section of the jetting devices, shown with the connections. Fig. 3 is an inverted plan view of the jet as shown in Fig. 1. Fig. 4 is a similar View to Fig. 3, but omitting the retaining collar and showing in dotted .7. Openings 9 are made outline the gas passages and the means for regulating and closing the gas passages.

Sim lar characters of reference are used to indlcate the same parts throughout the several views.

The improved jetincludes a body member 1 whlch has a reduced upper portion 2 for making connections either with a tubular connection 3 or with the collar 4. The collar 4: forms a seat for a plunger barrel. The object of the collar 4 is to support the plunger barrel for starting the flow of oil by pumping where the gas has been covered y water or oil until the gas will not start the oil to flowing. After the oil has been started to flowing through the plunger barrel by means of a pump, the plunger barrel may be removed and the oil will be forced out by the pressure of the natural gas. The collar 4 has a beveled seat 5 for the plunger barrel. The part 2 is also for service as a rope socket .neck for fishing out the jet in case of necessity. The jet 1 has a passage 6 for the upward flow of oil. The oil comes through a pipe 7 which may extend down any suitabledistance in the oil sands and is perforated for the intake of oil. A sleeve 8 is screwed on the lower end of the jetting devices for collecting the gas about the pipe in the body 1 at inclines so that gas may pass through the member 1 somewhat in the direction of the flowing oil so that the gas will be pushing upwardly when it strikes the column of upward flowing oil. Means are provided for regulating the amount of gas that may pass through the openings 9. A sleeve 10 is in place by a collar 14 and a set screw 15 which binds the collar 14 to the reduced body portion 16. Considering Fig. 4, when the set screwor lug 12 is at the position a, the openings 13 and 9 are both open and registering with each for the passage of'gas. When the sleeve is turned so that the lug 12 is in position b, the openings? are closed.

'mounted on the body 1 and is rotatable Theiopenings 9 can be opened more or less according to the gas pressure.

If there is no gas pressure which can be used, the'openings .9 can be closed andthe pump used as other pumps which use gas or air or steam for pumping purposes. The body 1 has a threaded opening 17 for receiving a tube for introducing air or steam or gas from, the surface. The collar or sleeve-1O has openings 18 for passage of air, steam, or gas into the oil line. In case it is necessary to use a pumping element from the surface, the collar or sleeve 10 is rotated to close the openings 9 and to open the passages 18. The pumping element will come down the opening 17 and enter the annular space 19 about the body 1 so that the pumping element may enter the oil line radially from several directions. In this operation, there would be no pressure on the oil sands. Instead of introducing the pump-- ing element through opening 17 the pumping element may be introduced through an opening 20 through the sleeve 10 into the annular space 19. There would be no pressure on the oil sands in such operation.

Various changes in the sizes, proportions, and construction of the several parts may be made without departing from our invention.

What we claim, is, j 1. A jet for lifting oil from wells through a discharge pipe consisting of a body member havinga passage therethrough for oil and interposed between sections of a discharge pipe and having gas ducts leading from the lower end of said body up through portions of said body to said passage, means for collecting gas about the discharge pipe below saidbody at said ducts, and means for closing or partly closing said ducts.

2. A jet for lifting oil from wells through a discharge pipe consisting of a body having a passage therethrough and interposed between sections of the discharge pipe, and having gas ducts leading from the lower end of said body at an incline and terminating in said passage, means for closing or partly closing said gas ducts, means for directingv gas to said gas ducts, and means connected to the upper end of said body for starting the 3. A jet for lifting oil from wells through a discharge pipe having a body provided with an oil passage therethrough and to be interposed between sections of a discharge pipe and provided with gas ducts leading from the exterior inwardly at a slight incline and upwardly, and a sleeve rotatable on the periphery of said-body and adapted to close or partly closesaid gas ducts andhaving inclined ducts adapted to register with said gas ducts and having an incline in the same d1rect1on as the incline asthe ducts,

in said body.

4. A jet for lifting oil from oil wells through a discharge pipe and provided with an oil passage therethrou h and to be interbody, a stud rigid with said body and said sleeve having a cut-out in the upper end to receive said stud for permitting a limited rotation of the sleeve on said body, a collar fixedly mountedon the lower end of Said body for supporting said sleeve against said shoulder, and means for collecting gas below said sleeve and body about an oil discharge pipe. 5. A jet for lifting oil from oil wells through a discharge pipe having a body provided with a passage therethrough and having upper'and lower ducts leading from the periphery thereof upwardly and inwardly to said passage-for a pumping element under force, means for directing a pump-ing element to said ducts, and a sleeve having a limited rotatable movement on said body for opening or partly opening said lower ducts and for closing said lower ducts. In testimony whereof, we set our hands this 16th day of September, 1921.
